PATENT JOHN THOMAS LEE, OF ATLANTA, GEORGIA.

SPECIFICATION forming part of Letters Patent No. 573,012, dated December15, 1896.

Application filed m 17, 1896. Serial No. 599,545. (No model.)

To all whom, it may concern.-

Beit known that I, JOHN THOMAS LEE, a citizen of the United States, anda resident of Atlanta, in the county of Fulton and State of Georgia,have invented certain new and useful Improvements in Fan Attachments forSewing-Machines, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part there of, inwhich similar numerals of reference indieate corresponding partswherever found throughout the several views.

The object of this invention is to provide an improved fan attachmentfor sewing-machines; and the invention is fully disclosed in thefollowing specification, of which the accompanying drawings form a part,in which- Figure 1 is an end view of a sewing-machine provided with myimprovement, part of the construction being broken away to better showthe location and operation of the attachment; and Fig. 2, a back view ofthe attachment removed.

In the drawings showing part of this specification I have shown at 5 anordinary sewing-machine of any desired form or construction, and in thepractice of my invention I provide a fan attachment therefor, whichconsists of a clamp 6, having two parallel jaws 7, by which theattachment is connected with the table 8 of the machine, and one of saidjaws is provided with a set-screw 9, and passing through the cross-headof the attachment is another set-screw, 10. Passing vertically throughthe separate jaws of the clamp and adapted to slide therein is a bar 11,which is provided at its lower end with a yoke 12, in which is mounted afriction-roller 13, and secured to the clamp at one side thereof is asleeve 1%, and the shaft of the roller 13 is provided with a head 15,and passing vertically through the sleeve 14 and the head 15 is a rod16, on the lower end of which is a smaller friction-roller 17, which isadapted to bear upon the side of the roller 13, near the perimeterthereof, and mounted on the rod 16, above the sleeve, is a collar 18,provided with a set-screw 19, by means of which the verti cal positionof the rod 16 is adjusted.

The rod 16 is provided at its upper end with a head 20, in the upper endof which is formed a socket which is adapted to receive the handle 21 ofa fan 22, which may be of the ordinary palm-leaf or any desired variety.

The friction-roller 13 is much larger than the roller 17 and is adaptedto bear upon and be operated by the drive-wheel 23 of the machine, andthe operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings and thefollowing statement thereof.

The fan attachment is connected with the table of the machine oppositethe operator or at the back thereof, and the rollers 13 and 17 arecomposed of rubber, rubber and canvas, or similar material, or areprovided with rubber perimeters, and the device is so adjusted that theroller 13 will bear upon the side of the drive-wheel The drive-wheel 23re volves the roller 13, and the roller 13 revolves the roller 17, whichoperates the rod 16 and revolves the fan, and the speed of the fan willdepend upon that of the rollers 13 and 17 and the size thereof.

This device is simple in construction and comparatively inexpensive andmay be quickly and easily attached to almost any form of sewing-machine,and the operation thereof does not interfere with the operation of themachine, and it is evident that changes in and modifications of theconstruction herein described may be made without departing from thespirit of my invention or sacrificing its advantages.

Having fully described my invention, I

claim as new and desire to secure by Letters Patent- The combinationwith a sewing-machine or similar article, of the herein-described fanattachment, adapted to be detachably connected therewith, consisting ofa clamp 6, provided with jaws, one of which is provided with a set-screw9 for attachment to the table of the machine, said clamp being providedwith another set-screw 10, a bar 11 mounted in openings formed in saidjaws, and adjustably secured thereto by the last-mentioned set-screw,said bar having formed on the lower end thereof a yoke 12, afriction-roller 13 mounted in said yoke, and adapted to bear on thedrive-wheel of the machine, a sleeve 14 connected with said clamp, a rod16 mounted in said sleeve and provided upon the lower end thereof with afriction-roller 17, said rod being; also journaled' in a head myinvention I have signed my name, in pres- 15 formed on said yoke 12, anda head 20 ence of the subscribing witnesses, this 13th mounted on theupper end of said rod 16, day of July, 1896. provided With a socket, anda, fan adapted to JOHN THOMAS LEE. 5 be secured on said head, and to beoperated Witnesses:

by the machine, as set forth. JOHN T. LYNCH,

In testimony that I claim the foregoing as A. MOD. XVILSON.
